The Ninth Circuit’s November 5^th decision in Coastal Environmental Rights Foundation, v. Naples Restaurant Group, LLC exploded onto the scene -- deepening an existing circuit split on whether a Clean Water Act citizen suit stays alive based solely only civil penalties once the alleged wrongful conduct ceases.  Consistent with the Eighth Circuit, the Ninth Circuit answered this question in the negative in Naples Restaurant.  The Second, Third, Fourth, Seventh and Eleventh Circuits have previously answered the question in the affirmative.  Overall, the key takeaway is for parties to make sure they are cognizant of the prevailing rule in their Circuit, and to be prepared to raise or respond to the arguments implicated by the Naples Restaurant opinion.

On June 30, 2025, the Supreme Court denied the Port of Tacoma (the “Port”) and SSA Terminals LLC's (“SSA”) petition for writ of certiorari to review the 9^th Circuit’s decision in Port of Tacoma v. Puget Soundkeeper Alliance addressing whether the Clean Water Act (“CWA”) authorizes citizens to enforce conditions of state-issued pollutant discharge permits adopted under state law that impose a greater scope of coverage than required by the CWA.  The 9th Circuit answered this question in the affirmative, holding that Washington's Industrial Stormwater General Permits (“ISGP”), a CWA National Pollutant Discharge Elimination System (“NPDES”) permit, required the Port and SSA to have the necessary stormwater controls across the entire West Sitcum Terminal (the “Terminal”).  The Supreme Court's recent decision to deny certiorari leaves litigants open to a patchwork of Circuit determinations on the scope of the CWA’s citizen suit provision.  Read More »

In an opinion published on December 18, 2024, the Montana Supreme Court found that a provision in the Montana Constitution providing for the right to a “clean and healthful environment” guarantees the right to a stable climate system.  In Held v.
